I’m in the middle of overhauling a vintage Singer 201-2 sewing machine, manufactured in the US in 1940. As I expected, the motor brushes need replacing, the oldfashioned leaf switch controlling the light is — at best — intermittent and needs a good cleaning, and the cottoninsulated wire is begging to be updated to fireproof silicon insulated wire. Old appliances — void of microcontrollers or even simple semiconductors — are a pleasure to tear down and rebuild. They’re fun as a solo weekend project, or, if you have someone you want to teach basic mechanics and electricity to, they make a good two or three weekend project. Even bringing an old toaster back to life can provide a sense of satisfaction.
